## ANALYST NARRATIVE
----------------------------------------------------------------
[Generated: 2026-05-01 15:13:28 UTC — narrative may predate facts above. Treat fields in TIMELINE / DETECTION EVIDENCE / INFRASTRUCTURE as authoritative if they differ from the prose below.]

PhishDestroy identifies leocosta1.github.io as an active credential theft phishing domain operating at an elevated risk level. This GitHub-hosted page impersonates legitimate services to harvest user login credentials, making it a persistent threat to unaware visitors.

This domain was flagged by 7 out of 95 VirusTotal security vendors, indicating significant malicious activity. It resolves to IP 185.199.108.153 via GitHub’s infrastructure, leveraging a valid Let’s Encrypt SSL certificate to appear trustworthy. As a recently registered GitHub Pages domain, it lacks historical trust signals and remains undetected by major blocklists despite its active distribution.

To mitigate risks, avoid interacting with leocosta1.github.io entirely. If credentials were entered, immediately reset passwords on all potentially affected accounts and enable two-factor authentication. Report the domain to GitHub and your security team to aid in its takedown. Use dedicated phishing detection tools to cross-verify suspicious pages before submission of any sensitive data.

## EVIDENCE HASHES
----------------------------------------------------------------
TLS cert SHA-256:      ea69bc711cb9d45698d2fdaa4854d7dc086acd3a9c350164909b688ac7c0631f

## SCORING METHODOLOGY
----------------------------------------------------------------
Composite score is NOT derived from VirusTotal alone. PhishDestroy aggregates:
  - VirusTotal positive ratio
  - Public blocklist consensus (MetaMask, ScamSniffer, OpenPhish, PhishTank, URLhaus,
    CryptoFirewall, SEAL, Polkadot, Enkrypt, Phishunt, DiscordPhishing, PhishingDB)
  - Cloaking detection (HTTP 666 or rendering delta between bot and real visitor)
  - DNS-filter consensus (Quad9, CleanBrowsing, NextDNS, AdGuard, Cloudflare, etc.)
  - AlienVault OTX pulses + Cloudflare Radar + Google Safe Browsing
  - URLScan / URLQuery verdicts
  - Brand-impersonation heuristics (DOM analysis of forms, logos, wording)
  - Known phishing-kit fingerprinting (favicon hash, JS obfuscation signatures)
  - Wallet-drainer family classification (Angel, MS, Rainbow, Pink, Inferno, ...)
  - Free-TLS vs paid-cert ratio (throwaway infrastructure signal)
  - Registrar/hosting abuse history (this registrar's track record)
  - Human researcher sign-off (volunteer takedown team)

A domain present in our database is ALREADY flagged. A low VT count by itself does
NOT mean the domain is safe — new scam domains routinely show 0/95 VT for their
first 7–30 days while actively draining wallets. Always cross-reference the composite
score and the individual indicators above, not just VT.
